Tom;
You are usually 'spot-on', but when you said:
>Courses like Butler National have passed by because they no longer get brownie points for being on Tour, and because they have been supplanted as the hardest tests of golf.
you lose me.
Butler is STILL one of the toughest tracks anywhere. It just needs a bit of TLC, which, I understand is on its way.
Butler needs an extensive tree management program and once they deepen their bunkers (ala Bethpage or Olympia Fields), they could host an Open tomorrow.
Except, of course, for their membership policies.
That being said, Butler belongs high amongst the 100 best Modern courses.
